[comp.dcom.telecom] Question About Area Code Split

sirakide%cell.mot.COM@uunet.uu.net> (01/03/90)

As I am sure most people know, the Chicago area has undergone an area
code split from 312 to 312 and 708.

Of course, most radio and tv ads now have to give an area code with
their phone numbers to keep things clear -- usually.

*Question* : I have heard several ads for stores where the phone
number is given out and the annoucer qualifies the number by saying,
"in either 708 or 312".  This is also true for most of the radio
request lines in Chicago: you can always dial them without an area
code. (I assume this will remain true after the grace period ends).
How is this done?

And as a related question: how do companies get phone numbers like
"dial LAWYERS" when the prefix for the spelled out number is not used
in the area that services the address of the business?

Thanks. (notice this article offers no opinion on Caller-ID)

[I have a feeling this is one of those questions that about 17 people
will answer.  Apologies for any unwanted duplication...]

There are several ways I can think of doing this; I'm not sure which,
if any, are *the* way it's done in any particular instance, but I
think they'd all work...

First of all, I don't *think* that a single exchange can overlap NPAs,
so that (for example) 708-888 and 312-888 would refer to the same
central office.  I can't find anything explicitly excluding this in my
references, though, so I could be mistaken -- if anyone knows this is
definitely the case, please let me know...

That means if (for example) you want your phone number to be 888-8888
in both 708 and 312, you have to have some sort of service in both 888
exchanges.

The simplest way I can see would be to get service in the appropriate
exchange in the "other" NPA (if your office is in 312, get service in
708) with the desired phone number, and forward it to your office.

A second solution would be to get foreign exchange (FX) service in the
other NPA, with dial-in capability and the appropriate phone number.

A third solution would be to get service in the other NPA with the
appropriate phone number and use private or leased facilities to tie
it to your office, but that's getting into the category of Serious
Hack.

Then, of course, there are all sorts of ways using services that
haven't been implemented yet, but that's not really relevant...

Same ways, I presume.

Thank you.  Sincerely.
